Title: Improvements in or relating to gas generating plant
IPC: C10J1/213
Filed: 1955-07-27
Abstract: 771,266. Gas manufacture. WAGNER, O. July 7, 1955 [July 9, 1954], No. 19624/55. Class 55 (2). In the carburetting of water-gas,. the carburetter is kept free from carbon deposits by arranging that during a part of the " blow " period, the blow gases, or a substantial portion of them, are by-passed around the carburetter, so that the air supplied to the carburetter is available for burning off the carbon left during the previous " run " period. The blow gases from the generator 1 pass via valves 25, 10, when the latter is open and a valve 11 is closed, to the top of the carburetter 2, and to a fixing chamber 3 when the valve 10 is shut and the valve 11 is open. Secondary air is admitted to the pipe 9 from the pipe 12. During the first 10-15 seconds of the blow, the valve 10 is open to effect combustion of the blow gases in the carburetter 2, and a consequent rapid heating of the refractory material. The valve 10 is then throttled and the valve 11 is opened, so that the major part of the blow gases pass directly to the fixing chamber 3, the part of blow gases which continue to pass through the carburetter serving only, on combustion with air, to maintain the temperature in the carburetter. The secondary air, preheated in the top of the carburetter, burns off the carbon at the lower part of the chamber 2. The combustion gas enters the bottom of the fixing chamber 3 and leaves at the top together with the blow gases which are combusted with secondary air supplied at 14. The gases are piped at 16 to a combustion chamber 4 where more air is supplied, and flow to a boiler 5 and stack 17. Before the end of the blow, the valve 10 is opened and the valve 11 is closed, so that all the blow gases pass through the carburetter and are burnt therein, residual air being thereby scavenged before the " run " is started. The water gas is piped at 18 to the top of the carburetter where heavy oil is sprayed. The product gas leaves at the top of the chamber 3 and passes through a trap 7.

Title: Improvements in machines for measuring cloth and the like
IPC: G01B5/04
Filed: 1922-07-24
Abstract: 207,226. Baldwin, C. E. July 24, 1922. Measuring.-In a machine for measuring cloth &c. the units indicator disc is movable away from the tens indicator disc during the zeroizing of the mechanism, the indicator discs being zeroized while they are separated. The indicator discs and a pointer for indicating fractions are zeroized simultaneously with the separation of the measuring and presser rollers for the insertion of cloth into the machine. The height of the instrument is adjusted to suit the operator by the insertion of a pillar between a clamp 26, Fig. 1, and a supporting-bracket 27, a screw passing through the pillar and securing the clamp and bracket together. The cloth to be measured is passed between a ribbed measuring-roller 37 and a movable presser roller 96 which is ribbed and may also be covered with india-rubber. When the end of fabric is in line with a starting arrow 112, the roller 96 is moved upwardly, and on the completion of the measurement, a knife 115 is moved into a slot 117 to slit the edge of the fabric to indicate the line along which it is to be severed.. Separating measuring and presser rollers. The presser roller 96 is mounted in slotted bearings in a cradle 97, Fig. 17, normally held in the raised position by a spring 100. When a hand-controlled lever 75 is moved inwardly, the roller 96 is lowered through a spring-controlled bell-crank lever 73 and a slotted link 93 engaging pins 95 on the cradle. When the fabric has been inserted, a lever 113, Figs. 1 and 17 is depressed and, through a lever 114. raises the lever 75 so that it is no longer held in its inner position by theengagement of a notch 76 with a part 83. Indicators, actuating. The measuring-roller 37, Fig. 17, drives through spur and bevel gearing, a wheel 41, Fig. 19, which is bored to receive a spring-controlled stem 42 having a nut 54 normally pressing a heart-shaped cam 44 into engagement with the wheel 41 so that a fractions pointer 43, Figs. 1 and 19, rotates therewith. The cam has a projection 45 which is adapted to advance a units wheel 46, Fig. 12, one step for each revolution of the pointer. The units wheel has a tooth 47 adapted to advance the tens wheel 48. The wheels 47, 48 are held against unwanted rotation by click springs 49, 50. Zeroizing-mechanism. The units disc 46, Fig. 12, and the click spring 50 for the tens wheel 48 are mounted on a slide 64, which is operated by the bell-crank lever 73, Fig. 17, which controlsthe separation of the measuring and presser rollers. When the slide is moved into the position shown in Fig. 12, a pin on the bell crank lever 73 turns a cam-piece 87, Fig. 19, to disconnect the heart-shaped cam 44 from the wheel 41, and a spring-controlled dog 66 on the slide engages the cam 44 to set the pointer 43 to zero. At the same time, a spring 65 on the slide and a fixed spring 50<1> engage heart-shaped cams 121, 120 on the tens and units indicator discs to set them to zero. The slide 64 is returned to its normal position by springs 79, 100, Fig. 17.

Filed: 1947-07-28
Abstract: 656,775. indicating-apparatus ; pressure gauges. DICKIE, A. B. July. 28, 1947, No. 20246. [Classes 106 (ii) and 106 (iv)] An instrument for indicating or recording a variable by a movable member over at least two ranges of movement on different scales comprising a rotary cam and follower is characterized in that the rotary cam is a disc having a continuous cam element in or on one face with different spiral characteristics in different portions of its length corresponding to the different ranges. The invention is shown applied to a steampressure gauge which comprises a Bourdon tube 3 with inlet 4 and movable end fixed to an arm 5 by screws 6 in slots 7. A turnbuckle 8 links the arm 5 and the tail 9 of a quadrant 10 which meshes with a pinion 11 rotatable with a disc 12 formed with a spiral cam slot 13 engaged by a follower. The follower may be a cranked arm 14 or roller carried by an arm and it may be slidable rectilinearly in guides in a radial direction with respect to the disc or it may be pivotal, the free end moving in an arc substantially radial to the disc. The arm 14 is connected to the tail 15 of a quadrant 16 meshing with a pinion 17 fixed to a spindle 18 for a pointer 19; preferably a coiled hair-spring 22 maintains engagement between the cam slot and follower, preventing backlash and chatter between quadrant 16 and pinion 17. The cam-engaging part of the follower or the follower itself may be releasably fixed for easy replacement. Different sections of the cam slot correspond to different sections of the scale. The section 20, Fig. 2, covering say 8/ 10 ths of the effective angle of rotation of the disc is of uniform spiral form and engagement therewith of the follower effects one half the displacement of the pointer over a uniformly marked scale, while the section 21 covering the remaining <SP>2</SP>/ 10 ths effects the remaining half of the displacement of the pointer over a uniform but more open scale. If desired, there may be only one spiral cam section, the first part of the slot being concentric with the disc and thus not imparting any motion to the pointer or there may be several spiral sections. The scale may move relative to the pointer.
